Im the same, but cant reset it as even next night if im tired, if i go earlier, still cant sleep! Think it started as, if i let him,my 17yr old would be up all night, and i was up till i could get him off internet & make him go bed, but then he goes on phone (games/txts) and i can hear him shuffling about next room door (im extremely sensitive to noise) so i stay awake too- (he was put on melatonin yrs ago by consultant for a bit)- but the body gets used to it & it stops working, but you could try it under your drs supervision i suppose?But this is same sleep pattern even when i get up earlier to make sure he's up to study online 3days a wk for college! (He wont manage otherwise as i suspect he doesn't fall asleep till about 6/7 then up for 9am start) but even on days without that i get broken sleep all the time for toilet.Ive always been a night owl but used to be 1-2 am.Now, this is ridiculous times.(maybe this sleep 'problem' runs in our family,theres at least 3 others amongst my older/younger GC like this.)But its definitely got worse in lockdown yes.
